Lake County, CA Noise Ordinances: Amplified Music & Events (2026)

There is no dedicated amplified-sound permit ordinance for general residential parties in the published unincorporated Lake County code. Amplified music is reached by two mechanisms. First, Section 41.11 of the Zoning Code Performance Standards limits sound at the receiving property line to a one-hour Leq of 55 dBA daytime / 45 dBA nighttime in residential and agricultural districts (Table 11.1), with 57/50 dBA limits where the receptor is a dwelling, hospital, school, library, or nursing home (Table 11.2). Notably, Section 41.11(e)(4) only exempts 'non-electronically amplified sounds at sporting, amusement, and entertainment events' - meaning electronically amplified music is not exempted and remains subject to the limits. Second, Section 13-3.1(e)(9) of the Chapter 13 nuisance code captures loud or unusual noises that offend the peace and quiet of persons of ordinary sensibilities and affect the entire neighborhood. Commercial and event venues that generate amplified music typically have it regulated through use-permit conditions of approval (the nuisance definition excludes noise already regulated through an approved use permit). Active loud parties are handled by the Lake County Sheriff and can be cited under California Penal Code Section 415 (disturbing the peace by loud and unreasonable noise). These rules apply only in unincorporated Lake County, not in Lakeport or Clearlake.
